Hi,
I am using Mapping Node to create a target message from a source message. I need to create a field at target side(corresponding field is not present at source) and populate with some value. Can anybody please help me to do that? I am new to mapping node.
Regards |

Yes, it's easy.
Just create a target field.
And then set it's expression to the value you need to populate it with.
There is no step 3. |

First my appolgy for not making the statement clear. The scenario is, in my source a particular element/complex type
may occur anywhere between 1 to 3. I will map all of them to target. But in case the source is less than 3, I need to
create exactlt 3 occurences at the target. Let's consider the example below, for each Request at source I need to create
a Response at target.RequestId is mapped to ResponseId and RequestVal is mapped to ResponseVal and I create an element
DummyResponse and populate the value as well.I have managed to make it work when there are 3 Request in my Source but
couldn't manage when number of Request in my Source is less than 3.
Source:
<?xml version="1.0" encoding="UTF-8"?>
<SourceMessage>
<Request>
<RequestId>1</RequestId>
<RequestVal>RequestInValue 1</RequestVal>
</Request>
</SourceMessage>
Target:
<?xml version="1.0" encoding="UTF-8"?>
<TargetMessage>
<Response>
<ResponseId>1</ResponseId>
<ResponseVal>RequestInValue 1</ResponseVal>
<DummyResponse>Dummy Response Value </DummyResponse>
</Response>
<Response>
<ResponseId>2</ResponseId>
<ResponseVal>RequestInValue 2</ResponseVal>
<DummyResponse>Dummy Response Value </DummyResponse>
</Response>
<Response>
<ResponseId>3</ResponseId>
<ResponseVal>RequestInValue 3</ResponseVal>
<DummyResponse>Dummy Response Value </DummyResponse>
</Response>
</TargetMessage>
Thanks In Advance |

As far as I know the 'for' loop in mapping only works on the occurrence of incoming elements.
You might have to use a combination of mapping and calling ESQL from mapping (to create the dummy elements). |
